but the clock frequency has not yet reached its speci ed ultimate stability.

Once the device is fully warmed up, the message is replaced by “10M” which means maximum

stability has now been achieved (the clock frequency stability meets speci cations) and the device

is ready for use.

When the device is  rst powered, these LEDs pulsate during the device’s warm-up period as the
